[Gcl-devel] Some random thoughts on future features

[Mike Thomas]

Hi Barton.

Thanks for your follow-up test with "cl::real".

Looks like GCL 2.6.5 (the stable release I tried yesterday) has problems 
with PCL and ANSI, as following on from your result I took CVS Maxima 
(using the Maxima-local batch file) built with CVS GCL and tried out 
Rays' original code (without the package manipulation I suggested) ie:

1. to_lisp()

2. Cut and paste Ray's original Lisp CLOS code

3. (to-maxima)

4. Cut and paste Ray's origional Maxima test code and I'm pleased to say 
that modulo some compiler noise, it worked as below.

I may not be subscribed to the Maxima list from this email address so it 
may take a while for this message to get through there.

Cheers

Mike Thomas.
